Today's in class assignment explores optimization of the Rosenbrock function, a standard test case for optimization algorithms. The function is f(x, y) = (a-x)2 + b(y-x2)2 The function has a global minimum at (a, a2) Assignment Create a Matlab function that calculates the Rosenbrock function. It should be passed four values (a, b, x, and y) 1. 2. Create a script that: Defines a and b (begin with a 1 and b 100) Creates arrays of x and y from -2
